Analog inputs can cause invalid values for Display Options

[Jesright73]

Describe the bug
Analog inputs are read as floats instead of integers in the Display Options step event, which can result in non-boolean settings having invalid values.

To Reproduce

1. Get analog input device (joystick, touch screen)
2. go to display settings in game
3. Change the setting of any non-boolean (e.g. Window Size, Metroid Counter, and Controller Tips) using the analog input.
4. Sometimes [!] appears. Doing this with Window Size can also result in bad screen scaling.

Expected behavior
Changing settings with analog should never cause invalid values.

Platform (please complete the following information):

• OS: Any

Game Version:
1.5.5

Additional context
Simple fix: round the analog input values in the step event of oOptionsDisplay

- input = (oControl.kRight - oControl.kLeft)
+ input = (ceil(oControl.kRight) - ceil(oControl.kLeft))
